Features

• Switch positions:CLOSED – OPEN – EARTHED

• Designed as a multi-chamberswitch with the functions

– Switch-disconnector and– Make-proof earthing switch

• Operation via gas-tightwelded-in metal bellows atthe front of the switchgearvessel

• Climate-independent con-tacts in the gas-filled switch-gear vessel

• Maintenance-free for indoorinstallation according toIEC 60 694 and VDE 0670-1000

• Individual secondaryequipment

• Switching functions asgeneral-purpose switch-disconnector (Class E3)according to

– IEC 60 265-1/VDE 0670-301 * and

– IEC 62 271-102/VDE 0671-102 *

Mode of operation

The switch shaft with themoving contacts rotates insidethe chamber containing thefixed contacts.

Compression vanes, whichrotate in conjunction with theoperating shaft, divide thearcing chamber into twosubchambers each of whichchanges in conjunction withthe rotation.

During the switching move-ment, the compression vanesgenerate a pressure differencebetween the subchambers. TheSF6 gas flows through a nozzle,causes a directional blow-out ofthe breaking arc and quenchesit rapidly.

Interlocking is not necessaryas the CLOSED and EARTHEDfunctions cannot be imple-mented simultaneously.

Closing operation

During the closing operation,the operating shaft with themoving contact blades changesfrom the “OPEN” to the“CLOSED” position.

The force of the spring-operated mechanism ensuresa high closing speed and areliable connection of the maincircuit.

The good dielectric strengthof the SF6 gas provides for de-layed pre-arcing onto the arcingcontacts of the fixed contacts.

Opening operation

During the opening operation,the SF6 gas is compressed inthe arcing chamber.

The compressed gas, whichflows from the nozzles of themoving contact blades, coolsdown the breaking arc betweenthe contacts and safelyquenches it in a fewmilliseconds.

The isolating distance estab-lished after breaking fulfills theconditions applicable toisolating distances in accordancewith– IEC 60 265-1/

VDE 0670-301 * and– IEC 60 694/

VDE 0670-1000 *

Due to the gas flow in thearcing chamber, which iscontrolled by the operatingmovement, both load currentsand minor no-load currents aresafely interrupted.

Earthing operation

“EARTHING” is implementedby moving the operating leverfrom the “OPEN” to the“EARTHED” position.

Features

• Mechanical service lifeexceeds 1000 operatingcycles

• Parts subjected to me-chanical stress are madeof non-rusting materials

• Lubricant-free bearings

• Manual operation withthe help of a slip-on lever,with a vertical liftingmovement (= detachablelever mechanism)

• Option:Motor operating mecha-nism

• Control board withaccordingly cut-outswitching gate:Prevents the three-posi-tion switch-disconnectorfrom being switched di-rectly from the “CLOSED”via the “OPEN” to the“EARTHED” position,hence operation of thethree-position switch-disconnector with theswitch-disconnectorfunction or with themake-proof earthingfunction.

12 Siemens HA 40.1 · 2007



Manual operating mechanism(detachable lever mechanism)

The three-position switch-disconnector is operated via ametal bellows rocker, which iswelded gas-tight with the switch-gear vessel.

Spring-operated mechanism

The spring-operated mechanismis used for three-position switch-disconnectors in ring-mainfeeders (as ring-main switches).

The switching movements areperformed independently of theoperating speed.

Spring-operated/stored-energymechanism

The spring-operated/stored-energy mechanism is used forthree-position switch-discon-nectors in transformer feeders(as transformer switches).

The switching operations arethe same as for the spring-operated mechanism. Anenergy store is available for trip-ping with the help of a trippingHV HRC fuse or via the shuntrelease.

No additional charging proce-dure is required for the energystore. This energy store isalready charged by the switch-ing operation from the“TRIPPED” position to the“OPEN” position. The pre-charged energy store ensuresthat the switch-disconnector/fuse combination can alsoswitch off all types of faults duringclosing.

After tripping, a red bar appearsin the switch position indicator.

Motor operating mechanism(option)

The manual operating mecha-nisms of 8DJ/8DH switchgearcan be equipped with motoroperating mechanisms forthe three-position switch-disconnector.

Operating voltages for motoroperating mechanisms:– 24, 48, 60, 110, 220 V DC– 50/60 Hz 110 and 230 V AC

Operation:

• Local operation by momen-tary-contact rotary controlswitch (option for 8DJ switch-gear) or by pushbutton(option)

• Remote operation (standard),applied to terminal

Shunt release (option)

Spring-operated/stored-energymechanisms can be equippedwith a shunt release. Remoteelectrical tripping of the three-position switch-disconnector ispossible via the magnet coilof the shunt release, e.g.transformer overtemperaturetripping.

To avoid thermal overloading ofthe shunt release in the eventof a continuous signal that maybe applied, the shunt release isswitched off via an auxiliaryswitch which is mechanically cou-pled with the three-positionswitch-disconnector.

Auxiliary switch (option)

Each operating mechanism ofthe three-position switch-disconnector can be optionallyequipped with an auxiliaryswitch for the switch positionindication:

• For 8DJ switchgear:– Switch-disconnector function:

Mode of operation

In the event that anHV HRC fuse link hastripped, the switch istripped via an articulationwhich is integrated intothe cover of the fusebox (see figure).

In the event that thefuse tripping fails, e.g.if the fuse has been in-serted incorrectly, thefuse box is protectedby thermal protection.The overpressure gen-erated by overheatingtrips the switch via thesilicon diaphragm in thecover of the fuse boxand via an articulation.This breaks the currentbefore the fuse box incursirreparable damage.

The above thermal protec-tion works independentlyof the type and design ofthe HV HRC fuse used.Like the fuse itself it ismaintenance-free and inde-pendent of any outside cli-matic effects.

Furthermore, the SiemensHV HRC fuses release thestriker pin depending onthe temperature and tripthe switch-disconnector asearly as in the fuse over-load range. Impermissibleheating of the fuse box canbe avoided in this way.

Access to andreplacement ofHV HRC fuse links

• Isolating andearthing the trans-former feeder

• Subsequent manualreplacement of theHV HRC fuse link

Ready-for-service indicator

Features

• Self-monitoring; easy to read

• Independent of temperatureand pressure variations

• Independent of site altitude

• Only responds to changes ingas density

• Option: Alarm switch“1 NO contact” for remoteelectrical indication

Mode of operation

For the ready-for-service indica-tor, a gas-tight measurementbox is installed on the inside ofthe switchgear vessel.

A coupling magnet, which isfitted to the bottom end of themeasurement box, transmitsits position to an outside arma-ture through the stainless-steelswitchgear vessel. This arma-ture moves the ready-for-ser-vice indicator of the switchgear.

While changes in the gasdensity during the loss of gas,which are decisive for theinsulating capacity, are dis-played, temperature-depen-dent changes in the gaspressure are not. The gas inthe measurement box has thesame temperature as that inthe switchgear.

The temperature effect iscompensated via the samepressure change in both gasvolumes.

Installation

Switchgear installationand pressure relief

It is possible to install 8DJ switchgear withresistance to internal arc faults and pressurerelief, e.g. in– Compact substations– Substations with control aisles– Switchgear buildings

Covers for pressure relief outlets and ducts,expanded metal assemblies, etc. do notconstitute a part of the switchgear. Theymust be supplied by the customer.

Absorber system (option)for 8DJ10, 8DJ20 and 8DH10 switchgear

To use maintenance-free and climate-independent switchgear in substation build-ings without internal arcing test, e.g. ”oldsubstations”, 8DJ10 and 8DJ20 switchgearcan be equipped with a pressure absorbersystem.

The pressure absorber system is enclosedand maintenance-free. As a “special coolingsystem”, it reduces the pressure-dependentand thermal effects of arc faults in theswitchgear vessel and the cable compart-ment, and thus protects both people andbuildings.

Switchgear withpressure absorber system (option)

• Type of installation:– Wall-standing arrangement for

8DJ10, 8DJ20 and 8DH10 switchgear– Option: Free-standing arrangement

for 8DH10 switchgear

• Feasibility:– 8DJ10 switchgear with a height of

1650 mm, up to 16 kA– 8DJ20 switchgear with a height of

1400 mm and 1760 mm, up to 16 kA– 8DH10 switchgear with a height of

1700 mm, up to 21 kA

Standards, specifications, guidelines

Standards

Dielectric strength

• The dielectric strength is veri-fied by testing the switchgearwith rated values of short-duration power-frequencywithstand voltage and light-ning impulse withstand volt-age according to IEC 60 694 /VDE 0670-1000 (see table“Dielectric strength”).

• The rated values are referredto sea level and to normalatmospheric conditions(1013 hPa, 20 °C, 11 g/m3

humidity in accordance withIEC 60 071 / VDE 0111).

• The dielectric strengthdecreases with increasingaltitude. For site altitudesabove 1000 m (above sealevel) the standards do notprovide any guidelines forthe insulation rating, but leavethis to the scope of specialarrangements.

All parts housed inside theswitchgear vessel which aresubjected to high voltage areSF6-insulated against theearthed enclosure.

The gas insulation at a relativepressure of 50 kPa (= 500 hPa)permits switchgear installationat any desired altitude above sealevel, without the dielectricstrength being adversely affect-ed. This also applies to the cableconnection when using cableT-plugs or cable elbow plugs(screened version) and to thebusbar for 8DH switchgear(screened version).

Dielectric strength forswitchgear with HV HRC fuses

• When HV HRC fuses areused, the conductors are ledout of the gas insulationthrough the bushing. Forthese connections in air, therated values (rated lightningimpulse withstand voltage,rated short-durationpower-frequency withstandvoltage) of the dielectricstrength are referred to nor-mal atmospheric conditions(1013 hPa, 20 °C, 11 g/m3

humidity), hence to sealevel, in accordance withIEC 60 071 / VDE 0111.

• Site altitude:

– As the altitude increases,the dielectric strength inair decreases due to thedecreasing air density. Thisreduction is permitted up toa site altitude of 1000 maccording to IEC and VDE.

– For site altitudes above1000 m, a higher insulationlevel must be selected. Itresults from the multiplicationof the rated insulation level for0 to 1000 m with the altitudecorrection factor Ka.

Standards

Internal arc classification(option)

The possibility of arc faults ingas-insulated switchgear type8DJ and 8DH is improbable anda mere fraction of that typicalof earlier switchgear types, dueto:

• Use of gas-filled switchgearcompartments

• Use of suitable switching de-vices such as three-positionswitches with make-proofearthing switch

• Logical mechanical interlocks

• Use of metal-coated voltagetransformers and three-phasering-core current transfor-mers

Other features of gas-insulatedswitchgear:

• There are no effects due toexternal influences, such as

– Pollution layers– Moisture– Small animals and foreign

matter

• Maloperation is practicallyexcluded due to logical arrange-ment of the operating me-chanism elements

• Short-circuit-proof feederearthing by means of thethree-position switch-disconnector

In the event of an arc faultat the cable connection,pressure relief is effecteddownwards into the cablebasement.

In the unlikely event of a faultwithin the switchgear vessel,the energy conversion in thecase of an internal arc fault isminor thanks to the gas insula-tion, i.e. approximately only 1/3compared to air. The escapinggases are discharged down-wards.

Pressure absorber system(option) for 8DJ10 **, 8DJ20 **and 8DH10 switchgear

For the use of maintenance-free and climate-independentswitchgear in substationbuildings without resistanceto internal arc faults, such ase.g. “old substations”,theswitchgear can be designedwith a modified pressure reliefsystem with absorbers.

Climate and environmentalinfluences

8DJ/8DH switchgear is comple-tely enclosed and insensitive toclimatic influences.

• Climatic tests fulfilled inaccordance with IEC 60 932(report)

• All medium-voltage devices(except for HV HRC fuses) areinstalled in a gas-tight, weldedstainless-steel switchgearvessel which is filled withSF6 gas

• Live parts outside the switch-gear vessel are provided withsingle-pole enclosure

• At no point can creepagecurrents flow from high-voltage potentials to earth

• Operating mechanism partswhich are functionally impor-tant are made of corrosion-proof materials

• Bearings in operating mech-anisms are designed as dry-type bearings and do notrequire lubrication.

As a “special cooling system”,this maintenance-free pressureabsorber system reduces thepressure-dependent and ther-mal effects of internal arc faultsin switchgear vessels and cablecompartments, and thus pro-tects people and buildings.

The closed system is suitablefor both wall-standing and free-standing arrangement (only for8DH switchgear).

Internal arcing test

• Protection of operating per-sonnel by means of tests forverifying the internal arcclassification

• Internal arcing tests mustbe performed in accordancewith IEC 62 271-200 /VDE 0671-200 *

Criteria for internal arc faults

• Criteria according toIEC 62 271-200 /VDE 0671-200 with respectto the behaviour in case ofinternal arc faults

• Definitions of criteria:– Criterion 1

Correctly secured doors andcovers do not open. Limiteddeformations are accepted.

– Criterion 2No fragmentation of theenclosure. Projection of smallparts up to an individual massof 60 g, are accepted.

– Criterion 3Arcing does not cause holesin the accessible sides up toa height of 2 m.

– Criterion 4Horizontal and verticalindicators do no ignite due tothe effect of hot gases.

– Criterion 5The enclosure remainsconnected to its earthingpoint.

Optionally, the switchgear types8DJ and 8DH can be designedwith internal arc classification:

• Internal arc classification IAC

• Type of accessibility A (forauthorized personnel only)

• Accessible sides– Side F (front)– Side L (lateral)– Side R (rear), as option

for 8DH switchgear

• Arc test current up to21 kA/1 s

Type of service location

8DJ/8DH switchgear can beused as indoor installationsin accordance with IEC 61 936(Power installations exceeding1 kV AC) and VDE 0101:

• Outside lockable electricalservice locations at placeswhich are not accessible tothe public. Enclosures ofswitchgear can only beremoved with tools.

• Inside lockable electricalservice locations. A lockableelectrical service location is aplace outdoors or indoorsthat is reserved exclusivelyfor housing electrical equip-ment and which is keptunder lock and key. Access isrestricted to authorized per-sonnel and persons whohave been properlyinstructed in electricalengineering. Untrained orunskilled persons may onlyenter under the supervisionof authorized personnel orproperly instructed persons.
